4 Claims. (Cl. 18S-72) 'I'he present invention relates to bus or carwindow construction, and more particularly to an improved transomstructure, an object being to provide a structure which will permit ofthe 6 convenient removal of the glass and side felt channels, -forreplacement or other purposes, simply by the removal of the bottom railof the transom. Another object is to provide improved spring means forsupporting the transom glass in a way to effectually relieve it of thebody or post movement, so that strains from such movement will not tendto break or loosen the glass.

With the above and other objects in view, an embodiment of the inventionis 'shown in the accompanying drawing, and this embodiment will behereinafter more fully described with reference thereto, and theinvention will be finally pointed out in the claims.

As the construction, according to the invention, is the same at eachside, only one side will be shown in the illustrated adaptation of theinvention.

In the drawing:

Fig. 1 is a fragmentary outside elevation of the transom structureaccording to the invention, and showing the upper portion of the movablewindow sash.

Fig. 2 is a vertical sectional view, taken along the line 2--2 of Fig.1.

Fig. 3 is a horizontal sectional view, taken along the line 3-3 of Fig.2.

Fig. 4 is a horizontal sectional view, taken along the line 4-4 of Fig.2.

Fig. 5 is a reduced outside elevation of one end of the transom, theparts being shown in their assembled relation, and

Fig. 6 is a similar view showing the glass together vwith the bottomrail and side channels partially removed.

Similar numerals of reference will be used to denote like parts in theseveral gures of the drawing.

Referring to the drawing, 1 represents the side post of the windowcasing, and 2 denotes the top moulding, the latter being relativelynarrower than the post 1 and having its outer wall disposed in flushrelation with the outer wall of the post. The transom, according to theinvention is disposed within the upper end of the frame in the planebelow the moulding 2, as will presently more fully appear, andrearwardly of the transom the channel 3 for the movable window sash 4 ismounted on the post 1.

The top channel rail 5 of the transom is of inverted U-shape incross-section and is connected to the under side of the moulding 2 bymeans of an upwardly projecting ange extension 6, ush with its inner legand secured to the inner wall of the moulding by means of screws 7. Alayer of cement 8 is interposed between the 60 moulding 2 and the toprail 5. A felt channel strip 9, for receiving the upper edge of theglass, is retained in the top rail by inwardly projecting anges 10 and11 at the lower edges of its sides.

The side channel rails 12 (only one of which is 65 shown) are also ofU-shape in cross section and are secured to the posts 1 by screws 13. Abowed leaf spring 14 is riveted or otherwise suitably secured in thebase of the spring preferably having bowed extensions, as shown,extending upwardly and downwardly from a at intermediate portion. Theinner wall of the side rail is provided at its end with a forwardlyprojecting lip 15 while the outer wall hasits end outwardly oset andfolded inwardly upon itself, as at 16. The parts of the transom thus fardescribed are xed with relation to the casing, while the parts now to bedescribed are removable.

The glass 17 has its side edges contained in felt channels 18, and thesechannels are backed by a metal retaining strip which has a portion 19that extends behind the channel and an outer portion 20 that extendsalong the outer face of the channel, the strip being clamped to the feltchannel by flanging over its ends, as at 21 and 85 22, upon the innerand .front faces of the felt channel, the flange 21 being pressed intothe felt so that it is ush with said inner face.

The lower edge of the glass is bound with glazing tape 23 and isinserted into the channel bot- 90 tom rail 24, which is of U-shape crosssection and is provided upon the inner surfaces of its side withlongitudinal ribs 25--25 that act as stops to limit the extent to whichthe glass may be inserted, and also reinforce the sides of the railagainst the tendency to bow as the sides are sprung during the pressingin of the glass. The inner wall of the rail is provided with a dovetailgroove 26 in whichis set a rubber sealing strip 27 adapted to engage theupper rail of the movable window sash 4, in the closed position of thelatter. The glass together with the side felt channels and the bottomrail, are put in. place simply by sliding the side channels upwardly inthe xed side rails 12 to a point where the upper edge of the 105 glassis rmly seated in the top felt channel 9, the bow springs beingcompressed and through pressure upon the portion 19 of the metalretaining strip pressing the felt channel 18 against the flange 15.

Angle retaining brackets 28 are thereupon se- -cured by screws 29 to thepost 1 beneath each end of the bottom rail, and the transom is thusretained in place, it being only necessary to remove these brackets inorder to remove the glass. Fig. 6 shows the manner in which the glasswith its side channels and bottom rail is removed or inserted.

It will be observed that the felt channel 18 has its inner leg directlyengaged with the retaining ange 15 of the side rail, while themetal-retaining strip 19-20 upon which the pressure o! the spring 14 isexerted is restrained only by the felt channel, there being nolimitingmeans upon the side rail 12 to oppose the pressure of. the spring uponsaidstrip. The glass is thus eilectually insulated against the strain ofbody or post movements, and atight ilt is at all times securedirrespective of dimensional variations or changes due to shrinkage ofthe felt or other causes. Should the glass be broken it may be veryeasily and quickly removed and replaced without disturbing any otherparts of the window structure.

I have illustrated and described a preferred and satisfactory embodimentof the invention, but it will be obvious that changes may be madetherein, within the spirit and scope thereof,.as defined in the appendedclaims.

Having thus described my invention what I claim and desire to secure byLetters Patent is:-

1. In a window transom construction, a frame, a top channel rail securedin the upper end of said frame, side channel rails secured to the sidesof said frame'having fixed inner and outer legs and open at their lowerends, there being a vertical free space beneath said lower ends; a glasssash, a bottom channel rail engaged upon the lower edge of said glasssash, said sash adapted to be vertically engaged with said side railsand said tcp rail through vertical movement in said free space, andremovable retaining means secured to said frame beneath the ends of saidbottom rail.
